Samsung’s Galaxy S10 sensor fooled by 3D printed fingerprint

It seems like all the security measures like in-display fingerprint scanning and 3D face locks on our smartphones are not as secure as we think.

A new report suggests that Samsung’s recent flagship phone, the Galaxy S10, can be easily fooled by a fake fingerprint.

In a post on Imgur, user darkshark outlined his project: he took a picture of his fingerprint on a wineglass, processed it in Photoshop and made a model using 3Ds Max that allowed him to extrude the lines in the picture into a 3D version.

After a 13-minute print (and three attempts with some tweaks), he was able to print out a version of his fingerprint that fooled the phone’s sensor.

This certainly isn’t the first time that someone has found a way to get around a phone’s sensors. Police officers used a 3D print in 2016 to get into a murder victim’s phone, while a cyber-security firm used a $150 face mask to beat Apple’s FaceID on an iPhone X in 2017.

The raises questions about how secure biometric authentication is these days, even when companies make high claims regarding their accuracy.
